Infrared stability of quarkyonic matter with the 1/p^4 confinement

Abstract

We demonstrate an exact cancellation of the infrared divergences in the color-singlet quarkyonic matter with the 1/p^4 Coulomb-like confining interaction both in the chiral symmetry broken and restored regimes.

Comments: A comment related to a choice of the infrared regularization as well as a couple of footnotes and one equation have been added. To appear in PRD
